The Christian creed is encapsulated in the Apostle's Creed, affirming beliefs in God the Father, Jesus Christ, the Holy Ghost, the Church, forgiveness, resurrection, and eternal life. The Lord's Prayer serves as the model prayer for Christians, emphasizing God's kingdom, will, provision, forgiveness, and deliverance. The Christian moral law is summarized in the Ten Commandments, focusing on worshiping God alone, honoring parents, and loving others, as well as Jesus' command to love God and one another.

David Shelby Corlett emphasizes the significance of the Holy Bible as the sacred book of Christianity, consisting of sixty-six books of the Old and New Testaments, given through divine inspiration. The message of the Bible is revealed through the inerrant Scriptures, guiding believers in all matters essential for salvation and pointing to faith in Christ Jesus for eternal life. The divine inspiration of the Bible is supported by the declarations of God's messengers, fulfilled prophecies, moral quality, spiritual value, unity in redemptive message, and the transformative power it holds for all who engage with it.

David Shelby Corlett preaches on the Christian belief in God, emphasizing the belief in one eternally existent, infinite God who is sovereign of the universe, as revealed in scriptures like Deuteronomy 6:4 and Psalms 90:2. The nature of God as a Spirit, Triune in essential being, is highlighted through verses like John 4:24 and Matthew 28:19. The sermon explores how the existence of God is known through His creative acts, providential care, and the revelation in the Holy Scriptures, as seen in Romans 1:20 and Psalms 145:9. The Fatherhood of God is revealed in His love, power, and provision, as shown in Titus 3:4 and John 5:45.

David Shelby Corlett preaches on the origin of man, emphasizing that God created man in His own image, forming him from the dust of the ground and breathing life into him. Man was given moral responsibility to choose between right and wrong, as seen in the command to be fruitful and multiply while avoiding the tree of knowledge of good and evil. Despite man's fall from his original moral state due to disobedience, God's attitude towards fallen man is one of love and compassion, offering salvation through Jesus Christ.

David Shelby Corlett preaches about the ground of salvation, emphasizing that Jesus Christ's atonement through His sufferings, shedding of blood, and death on the cross is the only basis for salvation, as stated in 2 Corinthians 5:19, 21 and 1 Peter 3:18. He also discusses the inclusivity of the atonement for all individuals, citing John 1:29 and Romans 10:12, 13. Furthermore, he delves into the concept of salvation, sin, original sin, and the necessity of repentance and faith for salvation, drawing from various Bible verses.

David Shelby Corlett preaches about the Church of God, emphasizing that it is composed of spiritually regenerate individuals whose names are written in heaven, and it is a spiritual organism where believers are incorporated by the Spirit. The Church belongs to Christ, purchased by His blood, and is called the Bride of Christ. Its mission is to be the pillar and ground of truth, the salt of the earth, and the light of the world, proclaiming the gospel of Christ. The Church is to be composed of regenerate individuals associated for holy fellowship and ministries, with the Church of the Nazarene seeking Christian fellowship, the conversion of sinners, and the preaching of the gospel to every creature.

David Shelby Corlett preaches on the standard of Christian living, emphasizing the importance of living upright, sober, and godly lives according to the moral law revealed in the Scriptures, seeking to glorify God in all aspects of life. Christians are called to glorify God in their bodies by recognizing that they are temples of the Holy Spirit, refraining from practices that do not honor God, and living in a way that reflects God's glory. The obligations for Christian growth include developing holiness, Christian virtues, and actively manifesting these in daily life, while the means for growth involve attending public worship, engaging in devotional exercises, and serving in Christian ministry.

David Shelby Corlett preaches about the kingdom of God as a present reality and a future hope, emphasizing the rule of Christ over His people through the Holy Spirit and the ultimate consummation of God's kingdom. Believers anticipate the second coming of Christ, where the living and the dead in Christ will be united with Him. The Christian view of death is seen as a transition to a new life in a glorified body, and the resurrection will bring both the just and the unjust back to life. Glorification represents the completion of salvation, transforming believers into the likeness of Christ's glorious body.

David Shelby Corlett delves into the foundation of the doctrine and experience of entire sanctification, emphasizing the crucial understanding of the nature of sin to grasp the concept of holiness. Sin is twofold, existing as a principle of evil within man's nature and as outward acts of disobedience against God's law. Man is born with a sinful nature inherited from Adam, making him prone to evil and incapable of righteousness without divine intervention.

David Shelby Corlett preaches about the purpose of Christ's coming into the world, emphasizing His mission to redeem humanity from sin. He delves into the significance of Christ's death, highlighting how it provided atonement for sin and purified believers. The sermon explores the sufficiency of Christ's sacrifice to settle humanity's debt of sin and the ample provision made in His atonement for the forgiveness and cleansing of sins, addressing the twofold nature of sin and the twofold provision in the atonement. Corlett emphasizes that there is no other source for redemption from sin except through Jesus Christ.

David Shelby Corlett preaches on the process of becoming a child of God through forgiveness and being born again, emphasizing the need for repentance, confession, and faith in Christ for the forgiveness of sins. He highlights that this forgiveness leads to justification, peace with God, and assurance of one's relationship with Him. The sermon also discusses the transformation that occurs within a born-again individual, making them a new creature and enabling them to live a life of righteousness.

David Shelby Corlett preaches about the ongoing inner conflict experienced by born-again Christians due to the presence of the sinful nature, highlighting the struggle for spiritual maturity, the limitations it imposes on one's service to God, and the inner clash of conflicting emotions and desires. He emphasizes that this sinful nature was evident even in the lives of the disciples of Jesus and individuals in the New Testament churches, affecting their faith and actions. Despite this struggle, the born-again Christian can have victory over sin through constant watchfulness and spiritual warfare, but God's ultimate plan is for His children to be delivered from all sin and to live in complete harmony with His will.

David Shelby Corlett preaches about the early church's emphasis on the second work of grace, highlighting instances where believers received the Holy Spirit as a second experience after conversion. The Apostle Paul also emphasized this second work of grace in his epistles, urging believers to cleanse themselves and perfect holiness. This second work of grace, or entire sanctification, fully solves the problem of sin in the nature by purging man's nature from all sinful tendency and pollution. It is not for backsliders or lukewarm Christians but for those walking in obedience to God, as it is necessary for believers to be fully sanctified to see the Lord.

David Shelby Corlett preaches on the call to holiness for God's children, emphasizing the need for a ready response and preparation for heart purity. He discusses the believer's attitude towards the sinful nature within, encouraging confession of the need for cleansing and reliance on Christ for purification. The sermon explores how believers can cleanse themselves through faith in the blood of Jesus and crucifying the flesh with its affections and lusts by identifying with Christ's crucifixion. Corlett also delves into the importance of complete consecration of one's life to God, highlighting the need for a full dedication that aligns the will with God's, leading to sanctification by faith.

David Shelby Corlett preaches on entire sanctification, explaining it as the work of grace by which God cleanses the born-again individual from the sinful nature remaining in the heart after new birth. This experience is provided through the sacrifice of Jesus and wrought in the heart by the Holy Spirit. Entire sanctification and the baptism with the Holy Spirit are one and the same experience, emphasizing cleansing and empowerment. The sanctified child of God has the sinful nature entirely removed, replaced by the fullness of the Holy Spirit, bringing inner peace and harmony with God's will.

David Shelby Corlett preaches about the sanctified child of God, equipped to live a life of holiness in a wicked world through the experience of entire sanctification provided by God's grace. The secret to living a holy life lies in complete dependence on the Holy Spirit for purity and maintaining a close relationship with Christ. Discipline, obedience, fellowship, and reliance on the Holy Spirit are essential for continued purity and success in Christian life and service.

David Shelby Corlett delves into the work and place of the Holy Spirit before and after His official advent on the day of Pentecost. He explains how the Holy Spirit has always been active in the world, from creation to the Old Testament period, preparing special messengers and working in the life and ministry of Jesus. Corlett emphasizes the significance of the Holy Spirit's manifestation and indwelling following Pentecost, highlighting the transformation and empowerment experienced by the disciples and early believers. He discusses various instances in the Acts of the Apostles where different groups received the Baptism with the Holy Spirit, emphasizing the importance of this second crisis experience for regenerated believers.

David Shelby Corlett delves into the distinctions between the work of the Holy Spirit in regeneration and in His Pentecostal baptism. The Scriptures emphasize being 'born of the Spirit' as the quickening of the spiritual nature, making believers new creatures in Christ Jesus. While 'adoption' signifies the relationship of the 'born again' individual to God and His family, where the Spirit bears witness that they are children of God. Jesus' analogy of the vine and branches highlights the believer's union with Him, drawing life and strength to bear fruit through abiding in Him.

David Shelby Corlett preaches about the inner warfare within the heart of a born-again Christian, emphasizing the need for the baptism with the Holy Spirit to overcome the struggle between the flesh and the Spirit. This conflict hinders believers from fully living out their Christian faith and being the victorious, joyous, and whole-hearted Christians God desires them to be. The presence of carnal dispositions prevents believers from doing what they desire as Christians and saps their spiritual life, power, and strength.

David Shelby Corlett preaches on the necessity of full surrender to God for the Holy Spirit to fully possess and fill our lives. Using the analogy of a home with a former resident still present, he explains how God desires to fully possess His temple, but the presence of 'the flesh' hinders this. Just as a homeowner must fully occupy his house after the former resident vacates, believers must put to death the deeds of the flesh and dedicate their entire being to God for the Holy Spirit to baptize and fill them completely.

David Shelby Corlett emphasizes the importance of making a full consecration or abandonment of oneself to God in order to receive the baptism with the Holy Spirit. This consecration goes beyond surrendering one's will and possessions; it involves yielding the entire life, body, soul, and spirit into God's hands for His Spirit to fill. It requires a deep commitment where Jesus rules without a rival in our hearts, signifying a complete ownership by God.

David Shelby Corlett emphasizes the importance of earnest desire and wholehearted seeking in receiving the baptism with the Holy Spirit. He highlights how many fall short in their pursuit due to a lack of genuine heart desire and specificity in their seeking. Corlett stresses the need for desperation and perseverance in asking for the fullness of the Holy Spirit, pointing out that half-hearted seeking will not lead to this divine experience. He underscores that only those who are definite and earnest in their seeking will receive the fullness of the Spirit.

David Shelby Corlett preaches on the connection between heart purity and the baptism with the Holy Spirit, emphasizing that true evidence of this baptism is the purification of the heart by faith. He highlights how the Holy Spirit guards against counterfeits, showing that speaking in tongues is not the ultimate evidence, but rather the purity of the heart. Corlett explains that heart purity, synonymous with entire sanctification, is achieved through the filling of the Holy Spirit, who dispels all that is carnal and fleshly, bringing unity and a central desire to do God's will.

David Shelby Corlett preaches about the enduement of power that comes with baptism, emphasizing that this power is sourced from the Holy Spirit Himself. This power allows believers to be transformed from weak and hesitant individuals into bold and confident children of God, enabling them to trust in the Spirit's ability to work through them. The secret to spiritual power lies in the union of the Holy Ghost with the purified faculties of the human soul, leading to an utter abandonment to and cooperation with the Holy Spirit.

David Shelby Corlett preaches on the significance of being filled with the Spirit, emphasizing the need for a deep and precious relationship with God where our lives are entirely His and His Spirit fills us. This fullness is not a one-time event but a constant appropriation and perpetual reception, requiring a ceaseless thirst and dependence on God. Many Christians hunger for this experience but are hindered by prejudice or unwillingness to fully yield to the Lord. Corlett urges readers to seek the baptism with the Holy Spirit as a personal, inward dynamic encounter that purifies the heart and empowers victorious Christian living.
